To perform a statistical average only for values that fulfill a specific condition, which function should be used?

The function that should be used to perform a statistical average only for values that fulfill a specific condition is AVERAGEIF. This function allows you to calculate the average of a range of numbers while applying a specified condition or criterion. For example, if you have a list of sales figures and you want to find the average only for those sales that exceed a certain threshold, AVERAGEIF lets you define that condition and returns the average of just the qualifying values.

In contrast, the SUM function adds values together without any conditions, while the AVERAGE function computes the average of all values in a range, regardless of any criteria. The COUNT function simply counts the number of cells that contain numeric values, again without any conditions. Therefore, AVERAGEIF is specifically designed for scenarios where a conditional average is required, making it the most suitable choice for the question posed.
